I can't install packages using install_github() in R

[Uchepat]

Whenever I try to install a package using devtools:install_github() in RStudio, I always get the following error

Error: ERROR: no permission to install to directory.....

Example: I tried installing abbrevTexts package from github because it isn't on CRAN

devtools::install_github(repo = 'GitHub - edvardoss/abbrevTexts: Functions that will make life less sad when working with abbreviated text for multiclassification tasks')

install_github(repo = 'https://github.com/edvardoss/abbrevTexts')

I have tried updating permissions on every R folders but to no avail. I can install packages from CRAN using install.packages() easily and without problems

My .libPaths() shows 2 directories.

[1] "C:/Users/Admin/Documents/R/win-library/4.1"
[2] "C:/Program Files/R/R-4.1.0/library"

The first directory contains my packages. Please I need to know if this is an R problem or Windows permission issue and how best to fix it. This issue is really affecting my productivity. Help is really needed.

1. R version 4.1.0
2. RStudio version 2022.02.3 Build 492
3. HP Windows 10

You are trying to install a package to "C:/Users/Admin/Documents/R/win-library/4.1", where you don't have a permission to write. It seems you don't have admin rights. I'm surprised you can install with install.packages().

Either you change access rights to this directory, login as Admin, or specify and alternative location for your library:

.libPaths("/path/to/your/personal/library")

or use a lib option

install_github(repo = 'https://github.com/edvardoss/abbrevTexts', lib = "/path/to/your/personal/library")

I basically reset my laptop (which in turn reset Windows permissions) and the problem was solved. I can now install packages using install_github() and install _packages().
What a relief.
